A rare and enigmatic Greenland shark was discovered washed up on the shores of northwestern Ireland, leaving zoologist Emma Murphy astonished. These massive and ancient creatures are known for their elusiveness and typically inhabit the remote depths of the Arctic and North Atlantic oceans.
The National Museum of Ireland, where Murphy serves as a zoology curator, expressed immense excitement at the exceedingly rare sighting of this species in Irish waters. It marks the first known instance of a Greenland shark stranding on the coast of Ireland.
Following the find by a bystander near Sligo, the Irish Whale and Dolphin Group was alerted, initially mistaking the shark for a basking shark commonly found in the region. Subsequent identification confirmed it as a Greenland shark, prompting swift action from researchers at the National Museum of Ireland.
Ranked as one of the largest carnivorous shark species globally, the Greenland shark boasts an impressive average length of three-to-five meters, with some individuals reaching up to seven meters. Notably, it holds the title of the world’s longest-lived vertebrate, with lifespans exceeding 270 years, and the oldest documented specimen was estimated to be around 400 years old.
Despite their primary habitat being the cold waters of the Arctic and North Atlantic, including regions such as Quebec and Atlantic Canada, experts believe that Greenland sharks have a broader habitat range than commonly assumed. Due to their mobility and preference for cold temperatures, these sharks have been spotted in various locations, including Belize and the Gulf of Mexico.
Given their deep-sea dwelling nature, Greenland sharks are rarely encountered by humans, making sightings a rare and memorable experience. Murphy and her team were thrilled to witness the stranded shark up close, emphasizing its beauty and the unique opportunity to study such a magnificent creature.
Following the retrieval of the shark’s carcass with the help of local volunteers, researchers are conducting tests to determine its cause of death. The male shark, estimated to be around 150 years old and in good health, presents a fascinating subject for further study and preservation within the museum’s collection.
Despite uncertainties surrounding the shark’s origins, Ireland will serve as its final resting place, with plans in place to preserve and display the specimen for public viewing and education in the museum.
